| 摘 要： | 建立了轴对称矢量喷管的数学模型和带这种矢量喷管的发动机数学模型,研究了矢量喷管与发动机的共同工作,矢量喷管偏转角对高低压转子共同工作线的影响以及矢量喷管的几何尺寸对发动机共同工作线的影响。研究结果表明:对低涵道比涡扇发动机,矢量喷管偏转角较大时会引起低压转子共同工作线下移,矢量喷管的几何尺寸对低压转子共同工作线也有一定的影响

| Abstract: | The mathematical models of an axisymmetric thrust vectoring nozzle and an aeroengine with this nozzle are established.The co-operation between vectoring nozzle and engine is studied with the help of these models.The results show that deflection of the vectoring nozzle affects slightly the high-speed rotor co-operating line,and also affects slightly the low-speed rotor co-operating line when the deflecting angle of vectoring nozzle is small,but makes the co-operating line moves to downward when the deflecting angle is larger.The geometry size of vectoring nozzle has some influence on the low-speed rotor co-operating line. |
